Our son impressed me by talking earlier this evening about part five of the story, and the disappointing cliffhanger to part four. He’s really thinking constructively and creatively about the show, which makes me very happy. He was much happier with this installment, except, of course, for the ending, which sees the Master getting away again. It’s difficult to say just how effective an exit that would be in the real world. Surely the British Navy wouldn’t have a great deal of trouble tracking down a stolen hovercraft?
Honestly, parts five and six could have been compacted into one installment. There’s a lot of padding, and a lot of Jo being very loudly worried about the Doctor, and a lot of repetition. The civil servant of the month is just as gluttonous and cowardly, the talk about a lasting peace between humans and Sea Devils isn’t going to go anywhere, and there’s more stomping around the echoey underwater base.
But Pertwee and Delgado continue their beautiful, twinkling chemistry (the Doctor gets to say “reverse the polarity of the neutron flow” for the first time), and there’s a lot of well-directed action and explosions. “The Sea Devils” isn’t anybody’s favorite third Doctor story, but it certainly is entertaining, and I’m glad our son enjoyed it!
